Table of Contents

Introduction

The purpose of this publication is to provide general information about the federal tax laws that apply to small business owners who are sole proprietors and to statutory employees.

A sole proprietor is someone who owns an unincorporated business by himself or herself. However, if you are the sole member of a domestic limited liability company (LLC), you are not a sole proprietor if you elect to treat the LLC as a corporation. A statutory employee has a checkmark in box 13 of his or her Form W–2, Wage and Tax Statement. Statutory employees have to use Schedule C or C–EZ to report their wages and expenses.

To use this publication, you will generally need the following forms.

  • Form 1040 and its instructions.
  • Schedule C or C–EZ and its instructions.

See chapter 12 for information on ordering these forms.

Husband and wife business.

If you and your spouse jointly own and operate an unincorporated business and share in the profits and losses, you are partners in a partnership, whether or not you have a formal partnership agreement. Do not use Schedule C or C-EZ. Instead, file Form 1065. For more information, see Publication 541.

Exception. If you and your spouse wholly own an unincorporated business as community property under the community property laws of a state, foreign country, or U.S. possession, you may treat the business either as a sole proprietorship or a partnership. The only states with community property laws are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. A change in your reporting position will be treated as a conversion of the entity.
